O Believers! Do not go near Prayer in a drunken state until you are able to understand what you say. Nor (should you approach Prayer) until you bathe after total ablution becomes obligatory unless you are travelling. And if you are sick or on a journey or return from a call of nature or make sexual contact with (your) women and then fail to find water, clean yourselves by using pure soil. So wipe your faces and hands. Surely, Allah is Most Pardoning, Most Forgiving.
